Transmission Identification

[drperry]

Due to gross overloading of the piddly 4 speed (I knew it was going to happen, but oh well ), I managed to cook my transmission fluid with one trip with my trailer, so now it needs changing... It's still pink-ish, but it smells like wood... My transmission temperature peaked at 217*F.

Ambient temp was around 95*F, otherwise I think it might've survived

My problem is that the transmission pan doesn't have the model stamped into it... So I don't know if I have a 4L60E with a deep pan or a 4L70E.

Is the filter the same for both?

I do plan on buying an additional transmission cooler for the time being...

Do you have a 6.0?

 

[drperry]

No sir, I have a 5.3, so I'm leaning to having the 4L60/65... I miss the days when GM stamped their stuff

On a side note, fluid coolers are a LOT cheaper than I thought they'd be!

 

[66nova]

You have a 60 if you have the 5.3. To my knowledge, gm does not put the 65/70 behind the 5.3. Those went in denalis, SS, and Vmax trucks.

Thanks Bob!

I was pretty sure that I had the 60, but it's nice to have a second opinion

Now just have to baby it until payday and I can order the new fluid, filter, and cooler

If it survives... It's already shifting inconsistently... Some days good, others not so good...

Where are you in that kind of ambient temps? Key West Fl?

We do get summer here in Canada, you know

If the transmisison is damaged I recommend swapping up to a 4l80.

 

[66nova]

The 4l60 is not a bad transmission. Taken care of there is no reason it can't hold up extremely well.

A 4l80 is great, but more work and more expense. And, IMO overkill for most half tons unless you age getting ready to add a bunch of power and race it. A 60/65/70 should hold up just fine with the weights a half ton was designed for.

Rebuild it, stick a shift kit and a servo in it and get a good trans cooler.
